Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The tail gas in the prior art is directly discharged and cannot be reasonably recycled, which easily causes waste and is not conducive to energy conservation and environmental protection.

[0020] In view of this, the utility model provides an exhaust gas heat energy recovery structure, which can reheat the discharged exhaust gas to water through the cooperation between the circulation pipe, the cylinder and the heating pipe, take away the exhaust gas heat, and then use the external conveying device to discharge it to the inside of the processing equipment again, so that the water inside the heating equipment can be quickly heated up, thereby saving part of the fuel, making the exhaust gas can be effectively utilized, and at the same time avoiding the high temperature of the working environment.

[0021] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0022] Embodiment 1: Figure 1 , Figure 2 and Figure 4 It can be seen that an exhaust heat recovery structure includes a base 1, and a recovery unit is arranged on the top of the base 1; the recovery unit includes a water tank 2, a cylinder 16, an insulation shell 13, a circulation pipe 12, a fixed pipe 15, an input pipe 14, a round pipe 5 and a heat dissipation pipe 6; the water tank 2 is fixedly connected to the top of the base 1, and the inner wall of the water tank 2 is rotatably connected with the round pipe 5 through a sealed bearing, and the round pipe 5 penetrates the inner wall of the water tank 2, and a plurality of heat dissipation pipes 6 are installed on the outer wall of the round pipe 5, and an insulation shell 13 is arranged above the round pipe 5, and the inner wall of the insulation shell 13 is fixedly connected with the cylinder 16, and the input pipe 14 is installed on the side of the cylinder 16 away from the water tank 2, and the heat dissipation pipe 6 is installed through the input pipe The cooperation between 14 and the fixed pipe 15, when the staff fixes the fixed pipe 15 and the exhaust gas discharge pipe, the exhaust gas can enter the interior of the cylinder 16 through the input of the input pipe 14, and the staff starts the power supply of the input pipe 14. The end of the input pipe 14 away from the round pipe 5 is connected with the fixed pipe 15, and the outer wall of the cylinder 16 is wrapped with a circulation pipe 12. The input end and the output end of the circulation pipe 12 both penetrate the insulation shell 13. Through the cooperation between the round pipe 5 and the heat dissipation pipe 6, the water inside the water tank 2 can be further stirred and heated to improve the heating effect of the water. The output end of the circulation pipe 12 is plugged into the top of the water tank 2;

[0023] In the specific implementation process, it is worth pointing out that, through the cooperation between the input pipe 14 and the fixed pipe 15, when the staff fixes the fixed pipe 15 to the pipe for discharging exhaust gas, the exhaust gas can enter the interior of the cylinder 16 through the input of the input pipe 14, and the water inside the water tank 2 can be further stirred and heated through the cooperation between the round pipe 5 and the heat dissipation pipe 6, so as to improve the heating effect of the water. A water pump is installed at the output end of the circulation pipe 6, and the model of the water pump is not limited, as long as it meets the use requirements;

[0024] Further, the outer wall of the circular tube 5 is fixedly connected with a first gear 9, the outer wall of the first gear 9 is meshingly connected with a second gear 7, the top of the second gear 7 is fixedly connected with a servo motor 8, the model of the servo motor 8 is not limited, and it can meet the use requirements. When the output end of the servo motor 8 drives the second gear 7 to rotate, it can drive the first gear 9 to rotate, and then the rotation of the first gear 9 can drive the circular tube 5 to rotate inside the water tank 2. The servo motor 8 is fixedly connected to the top of the water tank 2, and the top of the circular tube 5 is rotatably connected with a bent pipe 10 through a sealed bearing, and the top of the bent pipe 10 is connected to the inner wall of the cylinder 16;

[0025] In the specific implementation process, it is worth pointing out that when the output end of the servo motor 8 drives the second gear 7 to rotate, it can drive the first gear 9 to rotate, and then the rotation of the first gear 9 can drive the round tube 5 to rotate inside the water tank 2;

[0026] Furthermore, a plurality of partitions 11 are installed on the inner wall of the cylinder 16. The function of the partitions 11 is to extend the travel distance of the exhaust gas inside the cylinder 16 and increase the heating time of the water. The top and bottom of the fixed pipe 15 are both threadedly connected with threaded rods 18. A drain pipe 19 is installed at the bottom of the water tank 2. The function of the drain pipe 19 is to discharge the water inside the water tank 2 and then transport it to the processing equipment again by an external transport device, so that the water inside the heating equipment is quickly heated, thereby saving a part of the fuel.

[0027] In the specific implementation process, it is worth pointing out that the function of the partition 11 is to extend the travel distance of the exhaust gas inside the cylinder 16 and increase the heating time of the water;

[0028] Specifically, when using the exhaust gas heat energy recovery structure, the staff first uses the threaded rod 18 to fix the fixed pipe 15 and the exhaust gas discharge pipe, and then the exhaust gas enters the interior of the cylinder 16 through the input pipe 14, so that the heat is dissipated to the outer wall of the cylinder 16. Then the staff adds water from the top of the circulation pipe 12, and pumps it in through the water pump. When the water circulates inside the circulation pipe 12, the heat emitted from the inside of the cylinder 16 can be absorbed to achieve the initial utilization of the exhaust gas heat. Then, when the exhaust gas and water enter the inside of the circular pipe 5 and the water tank 2 respectively, the staff should start the power supply of the servo motor 8, and use the output end of the servo motor 8 to drive the second gear 7 to rotate. At this time, the rotation of the second gear 7 can drive the first gear 9 to rotate, and then under the drive of the first gear 9, the circular pipe 5 can drive the heat dissipation pipe 6 to rotate inside the water tank 2 to heat the water for the second time, and the exhaust gas is finally discharged through the bottom of the circular pipe 5.

[0029] Embodiment 2: By Figure 1 and Figure 3 It can be seen that the inner wall of the circular tube 5 is provided with a fixed shell 17, and the inner wall of the fixed shell 17 is installed with a mesh plate 20. The specific mesh number of the mesh plate 20 is not limited, and it can meet the use requirements. An adsorption layer 3 is arranged below the mesh plate 20. The material of the adsorption layer 3 can be activated carbon. The function of the activated carbon is to adsorb harmful substances in the exhaust gas, thereby improving the safety of exhaust gas emissions. The adsorption layer 3 is installed on the inner wall of the fixed shell 17;

[0030] In the specific implementation process, it is worth pointing out that the material of the adsorption layer 3 can be activated carbon, and the function of the activated carbon is to adsorb harmful substances in the exhaust gas, thereby improving the safety of exhaust gas emissions;

[0031] Furthermore, protrusions 21 are provided on both sides of the outer wall of the fixed shell 17. The cooperation between the protrusions 21 and the slots 4 is to facilitate the staff to disassemble the fixed shell 17, so as to replace the adsorption layer 3. The protrusions 21 are connected to the circular tube 5 through the slots 4.

[0032] In the specific implementation process, it is worth pointing out that the cooperation between the protrusion 21 and the slot 4 is to facilitate the staff to disassemble the fixed shell 17, so as to replace the adsorption layer 3;

[0033] Specifically, based on the above embodiment, before the exhaust gas is discharged through the circular pipe 5, it needs to be filtered through the mesh plate 20 to filter out impurities in the exhaust gas, and then adsorbed by the adsorption layer 3 to purify the harmful substances in the exhaust gas to meet the emission standards. When the staff needs to replace the adsorption layer 3, the staff should pull the fixed shell 17 so that the protrusion 21 is elastically deformed by the force and separated from the slot 4, thereby completing the disassembly of the fixed shell 17.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions.
